Vitamin E prevents the oxidation of free radicals that may result in cell damage and it acts as an anti-blood clotting agent. A potent antioxidant, Vitamin E protects the body from tissue damage that may lead to degenerative diseases such as heart disease and cancer. It also promotes normal red-blood-cell formation and protects the body from premature aging. Jamieson Vitamin E 800 IU is made from soy, which is more bioavailable to the body and ultimately more efficiently absorbed than synthetic Vitamin E. It contains d-alpha tocopherol, the most biologically active form of Vitamin E.
